How Africans developed scientific knowledge of the deadly tsetse fly
Few animals are more problematic than the tiny African insect known to English speakers as the tsetse fly. This is the carrier of “sleeping sickness,” an often deadly neurological illness in humans, as well as a disease that has killed millions of cattle, reshaping the landscape and economy in some parts of the continent.
